71V3556SA166BG8

Overview

The 71V3556SA166BG8 is a synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5 Mbit organized as 128K x 36 bits. The device supports a maximum clock frequency of 166 MHz with an access time of 3.5 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 119-pin PBGA package measuring 14x22 mm.

Feature Summary

• Synchronous parallel interface architecture designed for high-speed data transfer
• Zero bus turnaround technology eliminates dead cycles during read-to-write transitions
• Supports standard 3.3V I/O levels for system compatibility

Applications

• High-performance networking equipment requiring low-latency buffering
• Telecommunications infrastructure systems
• Industrial control applications demanding reliable volatile memory

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as specific variants may not meet current environmental standards. Validate package integrity upon receipt, as moisture sensitivity level 3 requires strict handling protocols to prevent damage during soldering processes.

Selection Notes

Select this component when a 128K x 36 organization is required for synchronous memory applications. Ensure the design accommodates the 119-PBGA footprint and thermal characteristics. Verify that the system power supply strictly maintains the 3.135V to 3.465V range to guarantee stable operation at the specified 166 MHz clock speed.

Part Context

This part belongs to the 71V3556 family of synchronous SRAMs from Renesas. It shares architectural similarities with other members like the 71V3556SA166BGI8 but differs in packaging and specific suffix designations. The family is characterized by its ZBT technology and high-frequency capabilities for embedded memory solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the product's end-of-life status, direct replacements should be evaluated based on pin compatibility and electrical specifications rather than official cross-reference lists.
